Therefore, the shoe upper is traditionally washed with water, and an auxiliary agent for hardening the upper is added to the washing aqueous solution, and then the upper is flattened and dehydrated, and finally the upper is dried, calendered and cut. Get the finished upper. In the washing aqueous solution of the knitted upper, an auxiliary agent for hardening the upper is added. Although the tightness and flatness of the knitted upper can be improved, most of the auxiliary agent remains on the surface of the knitted upper, and only a small portion penetrates. The inner surface of the knitted upper fiber, on the one hand, causes the surface of the upper to be hard and rough, and the hand feel is poor. On the other hand, after the shoe is washed a few times, the auxiliary agent is gradually washed away, and the tightness and flatness of the upper are gradually removed. Will fall, causing slack deformation. Moreover, for double-sided jacquard knitted uppers, the wash-off of the auxiliaries can cause the two layers of the upper to detach from each other and arch.
